Greenhouse Gases Are Cleaned Out

When
human beings extract and burn fossil fuels such as coal, petroleum and
others, we cause/trigger the release of carbon Dioxide and other
heat-trapping “greenhouse gasses” into the atmosphere.

To get
going with my latest finding on this issue; on this “challenge”,
greenhouse gases undergo three main steps. To make it simple, let’s
start with step 1

Step 1:

When gases are released from
industries into the air, gases rise up. This rising of gasses occurs
because of the process buoyancy, in which indoor-to-outdoor air density
is different. Basically, at this stage, it involves greenhouse gases to
move from bodies (either from cars, industries, trains etc.) into the
atmosphere.

Step 2:

It was scientifically proven that the
more you rise above the earth surface, the cooler you become. And this
temperature almost drops at the rate of about 6.5 ˚C per km of the
increased height inside the troposphere. When these emissions get into
the atmosphere at their very top altitudes, they separate themselves in
layers. These layers are made because of density differences of the
gases and their chemical properties. For example, carbon dioxide gas
would rise up to the approximate altitude and any other carbon dioxide
coming will just combine/join that group right there. And then any other
different greenhouse gas like Nitrous oxide will form a different layer
that is either above/below that layer of carbon dioxide.

When all this is done, gases undergo a process called gas-condensation.

This
process involves when gas particles are initiated by the formation of
atomic/molecular clusters of that species within its gaseous volume.
These clusters are usually small and form more like a dust, but at a
very high altitude. When these gases form this dust like a cloud, we
currently refer it to as global warming, instead of referring to it as a
“gas cloud” because it is responsible of trapping heat between the
atmosphere and earth surface.

Step 3

In this step, the
local portion of the atmosphere on which the gas cloud was condensing
forms small particles that actually fall off from that high altitude
towards the earth surface. Too bad that it does not reach the earth
surface, but at a certain height, these particles actually combine/mix
with the surrounding air particles and forms a normal air. The gas-cloud
that was forming global warming (acting like an earth heat trapping
blanket) does no longer exist, but now it’s part of the cool fresh air
surrounding us here.

Steps are now completed.

To make it
clear, greenhouse gases that are in the atmosphere precipitates out from
the atmosphere. It does not stay there for the rest of the time to
continue with the warming process. To scientifically prove this, it was
proven that there are greenhouse gases that are referred to as a”
short-lived greenhouse gases” which are the gases with a shorter
atmospheric lifetime because they precipitates fairly quickly from the
atmosphere. This is because it was proven that they do not stay there
for a long time. It’s only that none of the scientist these days
realized about the precipitation of the greenhouse gases that are
exhaled into the atmosphere by the people.

In conclusion to this,
we have known that nature itself has a way of controlling the amount of
greenhouse gases in the atmosphere that after a thick cloud of
greenhouse gases that people release from their factories and other
machines is in the atmosphere, it precipitates out. Therefore, global
warming is not forever. Just for example if the day time is cloudy
enough at a specific location, the temperature increases in that region
because clouds have trapped in the heat. But after the rain, everything
becomes normal. Same applies to the effect on global warming.

Response:

There are many issues with this submission that makes it scientifically invalid. Let's start at the beginning.

Step 1:
Gases do not move from indoors to outdoors because of differences in density. Unless the structure is hermetically sealed, the air pressure inside a structure must be equal to the air pressure outside. There are many reasons why gases move from one place to another in the atmosphere and wind currents are the number one reason. Hot exhaust gases are less dense and will rise to some extent, but the winds will mix them up given some time. The layer of air we live in is called the troposphere and extends to about 15 km above the surface. This varies depending on latitude with the height being less at the poles and greater at the equator. A characteristic of the troposphere is how gases in this layer are nearly uniformly mixed by weather and winds. The density drops as you get higher, but the relative mixture stays pretty much the same. It is not until you get into the stratosphere and higher that gases begin to separate into layers.

Step 2:
Gas condensate occurs when there is a drop in pressure in a gas. It happens when the relative density of a mixture in the gas reaches a point where the principle gas cannot contain it (along the lines of 100% humidity). CO2 and other greenhouse gases are not subjected to this process in the atmosphere because it can take many years for them to be lifted to higher altitudes. The drop in pressure is, therefore, so slow as to be nearly constant pressure. Plus, even with rising CO2 levels, we are not anywhere near the saturation point of CO2 in the atmosphere. The best I can determine is that the condensate temperature for CO2 is in the minus-hundreds of degrees Celsius at atmospheric pressure. This warms up some as pressure drops, but is still somewhere around -100 degrees C even at a pressure of 10 mm (we are at 1000 mm for one standard air pressure).

So, there are no clouds of gas condensate. In fact, we know CO2 is well mixed within the atmosphere as a gas and we sample it on a routine basis, such as the station on Mauna Loa, Hawaii that gives us the Keeling Curve. We routinely survey the skies in various wavelengths and no CO2 clouds are detected. Obviously, these would be very easily detected in the IR wavelengths.

Global warming is caused when CO2 molecules absorb and then reemit IR radiation, slowing down the transit of that energy from Earth's surface to space. Clouds of water vapor act as an insulator in much the same way and provide positive feedback in this manner. They also provide negative feedback by reflecting incoming sunlight back into space.

Step 3:
There is no large scale precipitation of CO2 gas condensates as you claim. In fact, by your claim, as this condensate precipitated and became pressurized it would revert to a gaseous state and is mixed back into the atmosphere. So, even with your gas condensate cloud hypotheses, the level of CO2 in the atmosphere would have to go up.

It is true that greenhouse gases get removed from the atmosphere, but it takes time. For CO2, we are talking centuries, possibly even several thousands of years. But, eventually, it will be removed from the atmosphere. Other gases don't last that long. They may remain in the atmosphere from a few years to a few centuries, depending on the gas. This removal occurs because the gas molecule gets washed out by the rain and absorbed somewhere, or it gets broken down by sunlight or chemical reactions in the atmosphere.

You are partly correct in your conclusion, although for the wrong reason. Nature does have a way of removing greenhouse gases and about 50% of man made emissions are removed by nature every year.
